While we can't meet you in person until the health crisis ends, our volunteers are still active and available to assist you online.
We are currently offering virtual advice clinics, presentations and workshops via Zoom. Here are just a few of the many presentations we offer:
  • Houseplants: Our Constant Garden
  • Landscaping with Trees and Large Shrubs
  • Putting the Garden to Bed

We'll update this notice if things change. Meanwhile, stay safe, and happy gardening.
